Risk assessment for human health and ecosystems by exposure to chemicals is an important process to aid in the mitigation of affected areas. Generally, this process is carried out in isolated spots and therefore may be ineffective in mitigating. This chapter describes an architecture of a multi-agent system for environmental risk assessment in areas contaminated as often occur in mining, oil exploration, intensive agriculture and others. Plan multiple points in space-time matrix where each agent carries out exposure assessment and the exchange of information on toxicity, to characterize and classify risk in real time. Therefore, it is an architecture model with multi-agent that integrates ontology by semantic representation, classifies risks by decision rules by support vectors machines with multidimensional data. The result is an environment to exchange information that provides knowledge about the chemical contamination, which can assist in the planning and management of mitigation of the affected area.

According to Rebelo et. al (2014), decisions on risk management mainly depend on their evaluation on a scientific basis. This question is quite emphasized in the literature because it deals with the importance of the issue, and in particular on the use of toxicology to aid the environmental management systems of the productive sector.

The principal methodologies for risk assessment to health and the environment are available for (United States Environmental Protection Agency [USEPA] 1986, 1989, 2004), (Agency for Toxic Substances and Disease Registry [ATSDR], 2016), (World Health Organization [WHO], 2010), (European Union [EU], 2003), (Government of Canada [Canada] 2004, 2012) and (Government of Netherland [Netherland], 2009). In Brazil, the (Environmental Company of The State São Paulo [CETESB], 2001), remains important procedures for the evaluation process of the risk to human health.
